2M-311 Thick Maui Coin Club

These are “working sample” specimens I purchased from the original manufacturer a few years ago (I have a letter of provenance from the president of the company that states these are working samples and identifies me as the first purchaser). To the left is the bronze and the right is aluminum.

As you can plainly see the aluminum is thick (8 mm). This is the only known thick variety of 2M-311 in existence.
